ok need a little help. i have been hearing some detonation at about 5k rpm when im at w.o.t so i took it to a dyno shop to check it out and same thing when it hit about 5k it was detonating loud and the a/f was 12.1 from 5k till redline.on map A and stock boost. i dont know too much about what causes the detonating. did some searches but got no help. any help would be great.
what would caues the a/f to be 12.1 and how do i change it
and does that cause detonation or are they 2 seperate issues
mods:
turbo back exhaust, short ram intake, 1 step colder plugs, unichip
thanks
